Prolix proverbs

When I was in high school -- so, many years ago (how many is left as an exercise for the reader) -- my English teacher, Ms. Reinhardt, gave us a set of puzzles, familiar sayings in unfamiliar guise.  Amazingly enough, I kept my copy all these years, and just ran across it this evening while searching for something else.

I don't know what their origin is (I don't think she made them up), but wherever they're from, they're fun brain-teasers.  How many of them can you figure out?

1.  A lithoid form, whose onward course
Is shaped by gravitational force
Can scarce enjoy the consolation
Of bryophytic aggregation.

2. To carry haulm of cereal growth
The tylopod is nothing loath;
But just one haulm too many means
That dorsal fracture supervenes.

3.  When, nimbus-free, Sol marches by

Across the circumambient sky,

To graminiferous meads repair --

Your instant task awaits you there!

4.  There is no use in exhortation
To practice equine flagellation,
If vital forces did depart
And still the breath, and cease the heart. 

5.  That unit of the avian tribe

Whose movements one can circumscribe

In manu, as a pair will rate

Subarborially situate.

6.  For none who claims to represent

The Homo species sapient,

Will loiter Einstein's fourth dimension

Or sea's quotidian declension.

7.  Faced with material esculent

As source of liquid nourishment

Avoid excess; 'twill but displease

Of culinary expertise.

8.  Conducting to the watering place

A quadruped of equine race

Is simple; but he may not care

To practice imbibition there.

9.  The coroner observed: "Perpend,

The death of this, our feline friend,

Reflects preoccupation shown

With business other than his own."

10.  If little value his compunctions

Who arrogates clavigerous functions

When once from circumambient pen,

Is snatched its equine denizen.

Have fun!
